Abstract:
A facility management system and a method thereof using perspective definition metadata, and more specifically, to a facility management system and a method thereof using perspective definition metadata, in which a perspective definition metadata structure for interconnecting Building Information Modeling (BIM) and external Facility Management (FM) data considering variability and expandability from the perspective of a user is used to improve expandability of the system by extracting information required for the role of the user from diverse heterogeneous data sources so that management and reusability functions of the system can be maximized even after the system is developed.
Abstract:
A horizontal resistance of an underwater pile is measured using a horizontal load applying apparatus which applies a horizontal load to the underwater pile to measure a horizontal resistance of the underwater pile by changing a direction of a penetration force generated when a suction pile penetrates an underwater ground.
Abstract:
Disclosed herein is a meteorological observation system using vehicles. The meteorological observation system using vehicles includes a meteorological observation device embedded in each of the vehicles and configured to periodically detect surrounding weather information and to photograph weather conditions, the vehicle configured to run on a road using radar devices for detecting the front and right and left sides of the vehicle, that is, sensors for supporting driving and prevent a collision, and to provide mobility to the meteorological observation device, a meteorological server configured to collect pieces of the weather information from the meteorological observation devices moving in respective areas through wireless communication and to provide the pieces of weather information to a meteorological observation center, the meteorological observation center configured to use information, received from the meteorological server, as statistical data or meteorological observation and forecast data.
Abstract:
A method for preparing pellets from rice husk includes: grinding rice husk; adding ammonia water to a mixture of ethylene vinyl acetate and poly(vinylacetate) to prepare a mixed, liquid binder; mixing the mixed, binder with the ground rice husk to obtain a binder/rice husk mixture; extruding the binder/rice husk mixture through an extruder; and cooling the extruded mixture at room temperature.
Abstract:
The present invention provides a porous material having micropores capable of storing and releasing heat by phase change, which comprises a phase change material inserted into the micropores of a porous material medium such as activated carbon or silica gel so as to be capable of storing and releasing energy, and a preparation method thereof. The method comprises the steps of: pre-treating a porous material medium to remove impurities from the micropores of the porous material medium, thereby opening the micropores; pre-treating a phase change material to make it possible to insert the phase change material into the micropores of the porous material medium; inserting the pretreated phase change material into the pretreated porous material medium; filtering the porous material medium filled with the phase change material to remove the phase change material remaining after the insertion step; and washing the filtered material.

Abstract:
A filling material according to an embodiment of the invention includes: an outer cover material having elasticity; an expansion material being inserted into an inside of the outer cover material, wherein the expansion material being compressed when the inside of the outer cover material is evacuated; a nozzle being provided at one end of the outer cover material, wherein air is evacuated from the inside of the outer cover material or air is injected to the inside of the outer cover material to expand the outer cover material through the nozzle; and a stopper for blocking the nozzle in a state that the inside of the outer cover material is evacuated to maintain the inside of the outer cover material to be vacuous.
Abstract:
A rod-shaped FRP bar is manufactured with a fiber and a resin by using a nozzle (100) which includes an outer nozzle (11) having a penetration hole at its center and a plurality of middle nozzles (12) disposed at an inlet of the outer nozzle 11 so that one middle nozzle is located inside another middle nozzle with an interval. Fibers are supplied through a center hole of the middle nozzle located at an innermost location, through intervals between the middle nozzles and through intervals between the middle nozzles and the outer nozzle, thereby making a hybrid FRP bar (1) having a section in which the fibers configure a plurality of fiber distribution layers from the center of the FRP bar toward the outside.
Abstract:
Provided are a method of semi-quantitatively evaluating concrete carbonation including the steps of a specimen preparing step of preparing a concrete specimen for identifying a degree of carbonation, a carbonation depth measuring step of measuring a carbonation depth of the specimen by a method of promoting carbonation of the specimen using a carbonation promoting tester and applying an indicator, an X-ray diffraction (XRD) analyzing step of qualitatively analyzing components of the specimen by an XRD method after cutting the specimen from a top end to a predetermined depth and crushing the specimen. Thus, the method of the present invention may calculate the exposure time of concrete carbonation by converting the analysis result value of XRD to the result value of TG-DTA.
